Abstract

This study presents a multifunctional hydrogel engineered by integrating carbon dots (CDots) and lanthanide metal ions (Ln3+), which exhibits tunable multicolor fluorescence under dual-wavelength UV excitation (254 nm and 365 nm). Systematic characterization via scanning electron microscopy (SEM), mechanical analysis, and fluorescence spectroscopy revealed three key features: distinct chromatic transitions between excitation wavelengths, favorable mechanical robustness, and long-term stability. The programmable fluorescence behavior, achieved through precise Ln3+ stoichiometric control and CDot-mediated energy transfer mechanisms, enables optical encryption with dual-excitation modes. Furthermore, the hydrogel demonstrates visual ion detection capabilities, exhibiting rapid fluorescence responses toward Zn2+ and K+via specific coordination interactions. This dual-functional hydrogel advances the development of intelligent materials for anti-counterfeiting technologies and environmental monitoring applications.

碳点和稀土水凝胶在双波长紫外激发可调多色荧光中的应用
本研究提出了一种集成碳点(CDots)和镧系金属离子(Ln3+)的多功能水凝胶,该水凝胶在双波长紫外激发下(254 nm和365 nm)表现出可调谐的多色荧光。通过扫描电子显微镜(SEM)、力学分析和荧光光谱的系统表征揭示了三个关键特征:激发波长之间明显的色度转变、良好的机械鲁棒性和长期稳定性。通过精确的Ln3+化学计量控制和cdot介导的能量转移机制,实现了可编程荧光行为,实现了双激发模式的光学加密。此外,水凝胶具有视觉离子检测能力,通过特定的配位相互作用对Zn2+和K+表现出快速的荧光反应。这种双功能水凝胶推进了防伪技术和环境监测应用智能材料的发展。
